TECHNICAL NOTES
The SHM-14 employs an open loop architecture in order to
achieve its superior high-speed characteristics. The first stage
buffer amplifier, which charges the hold capacitor, incorporates the
sample-and-hold switch into its design. This technique allows for a
fast acquisition time which is not limited by slew current like the
traditional Schottky diode bridge switch. The output amplifier uses
a closed loop voltage feedback design which provides a low (0.3
,
typical) output impedance. Gain and linearity are not affected by
heavy loads.
The design has been optimized to achieve the high accuracy associ-
ated with fast transient responses over the full military temperature
range. During the track-to-hold transient, the integral nonlinearity is
not affected and the pedestal remains constant over the full ±2.5V
input range.
An external hold capacitor can be added to the 15pF internal hold
capacitor to obtain a lower droop rate (the droop rate is propor-
tional to the inverse of the total hold capacitor value) without
increasing transient response times by more than few ns. Settling
and acquisition times are typically increased by 5ns and 10ns
respectively for 47pF and 100pF external hold capacitors. The
external hold capacitor should not exceed 100pF.
